fix: use stdio-wrapper as bin entry and preserve credentials on workflow update (v2.45.1) (#695)

Switch the npm bin entry from index.js to stdio-wrapper.js to prevent
INFO-level logs from corrupting the JSON-RPC stdio transport. Also update
both publish scripts so the fix persists across releases. Fixes #693.

Preserve node credentials during full workflow updates. AI-generated node
updates typically omit credential references, causing the n8n API to reject
the PUT. The update handler now merges credentials from the current server-side
workflow when user-provided nodes lack them. Fixes #689.
